sourisdb is a crate designed to provide a size-optimised way of transmitting a key-value store. There are a variety of methods used to achieve this goal ranging from variable-size integers to niche optimisations all detailed within [values::Value].
The expected use-case is for web - in testing I've found this to be far more efficient than JSON whilst preserving type information AND providing additional types. Typically, SourisDB stores take around 25% less space than JSON objects even when minified.
sourisdb can also be used for storage on-disk as it is entirely byte-order-agnostic as it deliberately stores everything using little-endian bytes.
